Concerned about Murphy's energy level and eager to give Turner an uninterrupted string of at-bats, Collins said that the switch will be in effect on Saturday, as well.
"When you look at his last two years, one of them he didn't play at all, hardly," Collins said of Murphy. "The other one, last year, he got hurt and missed quite a bit of time. He's playing a new position. So I think not just physically, but mentally, the fact that he's at a new spot has worn him down a little bit because he plays every day as hard as anyone I've ever been around. He loves to play. He's a workaholic. I just think it's time for him to take a couple days."
Though Murphy told his manager that he felt well enough to play this weekend, the symptoms of fatigue were obvious to Collins. Since hitting his last home run on Aug. 8, Murphy has batted .122 with a .170 on-base percentage. Turner, meanwhile, has not started back-to-back games since June 20-22, making the move as much about giving him at-bats as it was about resting Murphy.
